Description
Technical field
The utility model belongs to assembled architecture technical field, and in particular to a kind of anti-freeze expansion assembling type base.
Background technique
Frost heave (frost heaving) is since water freezes to draw with the growth of ice body (especially convex lens shape ice body) in soil
Play soil expansion, earth's surface unevenly grand role.Frost heave generally results in ground and deforms, and forms frost heave mound.Frost heave,
Especially otherness frost heave is that engineering construction is caused to deform so that the main reason for destroying.Frost heave makes basic integral raising or part
It raises.Summer of being passed the winter repeatedly freezes, melts, buffering, and basis fracture is broken, and basis part frost heave cracks building, serious
There is crack, present wide at the top and narrow at the bottom, it is also possible to generate many cracks, it is inverted eight like that appearance is presented.Freeze shear force to generate basis
Lateral thrust makes basic lateral displacement.Strip footing local fracture, basis is lateral to generate vertical crack.Due to raising for basis
And displacement, support other walls generate crack, the position in crack and shape are different because of configuration and structure, have it is vertical, slanting,
Horizontal.Crack must be observed and carry out comprehensive analysis, be frost heave or sedimentation, just can determine that.Frost heave is basic to independent barnacle,
There may be localized raised fractures and lateral deduction.Concrete ground beam can be made to be broken, wall collapses.
Frost-heave force acts on building, structures and road, will cause very big destruction and serious economic loss.Freeze
There are mainly three types of expansive forces: tangent coordinate system, Normal frost heave and horizontal frost-heaving, and pulls out on the basis of making, and it is main to generate destruction
It is tangent coordinate system.Tangent coordinate system (tangential frost-heave forces) refer to foundation soil in freezing expansion, edge
Tangentially act on the power of basic side surface.Traditional architecture field is generally taken precautions against tangent coordinate system using inclined-plane basis, is being frozen
The stress on swollen effect lower inclined plane basis is clear, and durability is also very outstanding, and under multigelation, antifreezing expansion effect is basic
It is constant.But general inclined-plane foundation structure is more special, compares and is difficult to be connected with assembling type base, therefore is poorly suitable for big
Most assembled architectures.

Embodiment 1
A kind of anti-freeze expansion assembling type base, as shown in Figure 1, including center stand column 1, bottom plate 2 and column outline border 3, wherein bottom
The surface of plate 2 is equipped with column outline border 3, and the inside insertion center stand column 1 of column outline border 3 is up to the bottom of bottom plate 2；
As shown in Fig. 2, the surface of bottom plate 2 is equipped with the reinforced hole 4 of two groups of perforations straight down, two groups of reinforced holes 4 divide
Not Wei Yu bottom plate 2 both sides and bilateral symmetry, the center of bottom plate 2 be equipped with square hole 5, center stand column 1 can be inserted into agreeing with；
A kind of preferred scheme, as shown in figure 3, the bottom plate 2 is along the square hole 5 at center and two groups of reinforced holes of the right and left
4 it is removable be divided into two pieces of secondary floor plates 6, two pieces of secondary floor plates 6 are symmetrical.
As shown in figure 4, center stand column 1 is rectangle truncated rectangular pyramids structure, four sides are inclined-plane 7, there is a gradient, inclined-plane 7 by
It is gradually become smaller up to lower area, bottom can be inserted into the square hole 5 of bottom plate 2 with agreeing with；
As shown in Figure 5,6, column outline border 3 is rectangle truncated rectangular pyramids structure, top opening, it is internal be it is hollow, it is internal
Hollow space gradually becomes smaller straight down, and the center stand column 1 can be inserted with agreeing with, and two sides of the bottom are equipped with straight down
Reinforcing rod 10, the position of reinforcing rod 10 is corresponding with the position of two groups of reinforced holes 4 on 2 surface of bottom plate, four external sides
Face is inclined-plane 9, has the gradient, from top to bottom area becomes larger on inclined-plane 9.
It is assembled between center stand column 1 and column outline border 3 using piugging technology, the inclined-plane 7 and column outline border 3 of center stand column 1
Hollow internal four sides all there is the gradient, the gradient on inclined-plane 7 from top to bottom becomes smaller and the gradient of the hollow inside of column outline border 3
Equally.Frictional force between the two is utilized in such connection method, when column outline border 3 is by uplift force, center stand column 1
The gradient can prevent basic outline border from moving up.
Studies have shown that inclined-plane basis can effectively eliminate tangent coordinate system, protecting group when inclined-plane ratio is 1:7
Plinth.Therefore the gradient on inclined-plane 9 is 1:7；The value of slope on inclined-plane 7 does not require, opposite with the gradient of hollow inside of column outline border 3
It should.
